Answer 2

Answer:

0.000810537 <= 0.001. As error <= accuracy, we stop the iterations and use 0.8944275583 as the square root. So, we can say that the square root of 0.8 is 0.894 with an error smaller than 0.001 (in fact the error is 0.000810537). this means that the first 3 decimal places are correct.
